UNITED STATES PATENT OFFICE SAMUEL B. ORR, OF CIRCLEVILLE, OHIO.

WEIGI-IING-MACHINE FOR GRAIN.

Application filed February 19, 1915, Serial No. 9,400. Renewed January 4, 1917.

To all whom it may concern Be it known that I, SAMUEL B. ORR, a citizen of the Unlted States, residing at Circlevllle, in the county of Pickaway and State of Ohio, have invented certain new and useiul Improvements in WVe1gh1ng-Machines for Gram, of which the followlng 1s a specification.

This invention relates to weighing machines for grain or other substances but more particularly adapted for use in weigh ing husk corn, as the ears of the corn are con.- veyed from the h usking machine, and has for its object to provide means, in a manner as hereinafter set forth, for automatically weighing grain particularty huslr corn, in bulk, then automatically discharging the weighed material, at the same time actuating a register operating means, so as to indicate the number of weighings or the aggregate total of the material weighed, but more particularly to indicate the aggregate number of weighs.

Further objects of the invention are to provide an automatic weighing machine which is simple in its construction and arrangement, strong, durable, etlicient and convenient in its use, readily set up and comparatively inexpensive to manufacture.

lVith the foregoing and other objects in view the invention consists of the novel con struction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodi ment of the invention, but it is to be understood that changes, Variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a perspective view of an automatic weighing machine in accordance with this invention.

Fig. 2 is a cross sectional view of the weighing drum. 7

Fig. 3 is an elevation of the weighing drum.

Fig. 4: is a detail illustrating one end of one of the hinged supporting levers for the shaft of the weighing drum.

Referring to the drawings in detail the machine comprises'a rectangular supporting Specification of Letters Patent.

frame including two pairs of vertically disposed uprights. The uprights of one pair are indicated at 1 and 2.and the uprights of the other pair at 8 and 1. The upright 2 is connected to the upright by a longitudinally extending top bar 5 and the up right 1 is connected to the upright 3 by a loi'igitudinally extending top bar 6. Between the top bars 5 and 6 at one end is arranged a transverse top bar 7 and between the top bars 5 and (3 at the other end is arranged a transverse top bar 8. The top bars 5 and 8 are secured together in any suitable manner and the top bars and G are secured to the uprights 1, l-, in any suitable manner.

The upright 1 is connected to the upright 3 by a longitudinal brace which is secured to said uprights below the top bar 6 and the uprights 2, 4. are connected together by alongitudinal extending brace 10 which is arranged below the top bar The uprights 1 and 2 are connected together by a transverse brace 11 and the uprights 3 and 4: are connected together by a transverse brace 12.

The uprights 1. and 2 are each provided with a vertically disposed elongated rectangular slot 13 and through the said slots 13, extend the reduced ends 11, of a pair of longitudinally disposed supporting levers 15. The reduced ends 11 of the levers 15 project forwardly from the uprights 1 and 2. The other ends of the supporting levers 15 have a hinged connection therebetween and to uprights 3, l, as indicated at 16 and by such an arrangement the reduced ends 11 of the levers 15 can be swung down wardly when occasion so requires.

Mounted upon each of the supporting levers 15, centrally thereof, is a bearing 17, only one of which is shown, and journaled in the bearings 17 is a drum shaft 18.

Adjustably connected to the top bars 5 and 6, are the upper ends 19 of a pair of vertically disposed springs 20 and these latter have their lower ends 21 adjustably connected to the supporting levers 15. The function of the sprin s 20 is to normally maintain the supporting levers in the position as shown in Fig. 1 whereby the hinged connection will be closed. The ends 19 and 21 of the springs 20 are threaded as at 22 and engaging the saidthreaded ends are adjustable nuts 23 which are employed for to project through the bottom of the member 24, and said lower end 27 is threaded as at 28, and engaging with said threaded end 23 is an adjustable nut 529. The upper end of the spring 26 is extended a at 30 and which projects through a bracket 3i secured to the brace 11, by the hold fast devices The extended upper end 30 of the spring 56 is threaded as at 33 and engaging with said threaded end is an :uliustable nut 34:, the latter being arrai d above the braclmt 3i. angcd below the member llhc end :29 is an. in. The function of the spring 26 is to co act with the springs 20 to maintain the hinged connection between the supporting levers l5 and the uprights 3, t, closed and for further purposes to be presently referred to.

Secured to the shaft 18 is a drum 36, having a pair of pockets 3?, 38. The mouth of each of the pockets 37, 38 is permanently open. Carried by the periphery of the drum 36 is a stop member 39 for each pocket, adapted to engage a resilient retaining menr ber 40, which is carried by a transverse bar ll secured to the top bars 5, 6.

The springs 20, 26 are employed to nor mally maintain the reduced ends of the supporting levers 15 elevated so that the retaining member d0 will be in the path of the stop member 39, under such conditions, arresting movement of the drum whereby the drum will be set in the position as illustrated in Fig. 2.

It will be assumed that the drum 36 is in the position as shown in Fig. 2, and that the material is fed to the pocket 37, when the weight of the material in the pocket 37 overcomes the strength of the springs 20, 26, the supporting lever 15 will be swung downwardly and the hinged connection 16, under such conditions the stop member 39 can pass the resilient retaining member 40 and the material weighed in the pocket 37, will be dumped owing to the fact that the weight of the material will cause the drum 36 to revolve.

By way of example, it will be-assumed that the machine is to weigh a quantity of material of a weight of fifty pounds each, thereby it is obvious that when either of the pockets 37 or 38 receive material of a weight equal to fifty pounds, the strength of the springs 30, 26, will be overcome, the supportmg lever 15 swung downwardly on their hinged connections and the drum will be caused to revolve owing to the weight of the material.

One of the supporting levers may be provided with a conventional registering mechanism, as indicated at 4-2, whereby each half revolution will be registered to indicate a weigh.
